Null Pointer Dereference Where Null Comes From Condition at Ellie Hedditch blog

Null Pointer Dereference Where Null Comes From Condition. When you try to dereference a null pointer it means you are trying to address an object that isn't there. It’s trying to access a certain type of data, but finds something else instead (namely, nothing). The unary * operator performs indirection but there seems to be no definition of invalid pointer value that formally includes the null pointer. Here’s an example of a null pointer dereference from the common. Null pointer dereferencing can happen due to a variety of reasons, such as race conditions and programming oversights. A null pointer dereference occurs when a program ties to access the data stored at a memory location that is set to null, often resulting in an error or crash. In this article, we'll dive deep into what null pointer dereferences are, why they occur, and how to avoid them. This leads to undefined behaviour. The return value from a method is dereferenced without a null check, and the return value of that method is one that should. Buckle up, because we're about to.
